Method Summary

Modifier and Type	Method and Description
protected boolean	canProvideOutputStream() returns true when: a) the pipe might be able to accept an input by providing an OutputStream, and b) there are no side effects configured that prevent handing over its PipeRunResult to the calling pipe (e.g.
protected ChecksumPipe.ChecksumGenerator	createChecksumGenerator()
PipeRunResult	doPipe(Message message, PipeLineSession session) This is where the action takes place.
protected MessageOutputStream	provideOutputStream(PipeLineSession session) provide the outputstream, or null if a stream cannot be provided.
void	setCharset(String string) Character encoding to be used to encode message before calculating checksum.
void	setInputIsFile(boolean b) Deprecated.
void	setType(ChecksumPipe.ChecksumType value) Type of checksum to be calculated

Method Detail

createChecksumGenerator

protected ChecksumPipe.ChecksumGenerator createChecksumGenerator()
                                                          throws NoSuchAlgorithmException

Throws:

NoSuchAlgorithmException

doPipe

public PipeRunResult doPipe(Message message,
                            PipeLineSession session)
                     throws PipeRunException

Description copied from interface: IPipe

This is where the action takes place. Pipes may only throw a PipeRunException, to be handled by the caller of this object. Implementations must either consume the message, or pass it on to the next Pipe in the PipeRunResult. If the result of the Pipe does not depend on the input, like for the FixedResultPipe, the Pipe can schedule the input to be closed at session exit, by calling Message.closeOnCloseOf(PipeLineSession, String) This allows the previous Pipe to release any resources (e.g. connections) that it might have kept open until the message was consumed. Doing so avoids connections leaking from pools, while it enables efficient streaming processing of data while it is being read from a stream.

Throws:

PipeRunException

canProvideOutputStream

protected boolean canProvideOutputStream()

Description copied from class: StreamingPipe

returns true when: a) the pipe might be able to accept an input by providing an OutputStream, and b) there are no side effects configured that prevent handing over its PipeRunResult to the calling pipe (e.g. storeResultInSessionKey) c) there are no side effects that require the input to be available at the end of the pipe (e.g. preserveInput=true) d) there are no parameters that require the input value or context (b and c are implemented by PipeProcessors, that do not support outputStreaming)

Overrides:

canProvideOutputStream in class StreamingPipe

provideOutputStream

protected MessageOutputStream provideOutputStream(PipeLineSession session)
                                           throws StreamingException

Description copied from class: StreamingPipe

provide the outputstream, or null if a stream cannot be provided. Implementations should provide a forward target by calling StreamingPipe.getNextPipe().

Overrides:

provideOutputStream in class StreamingPipe

Throws:

StreamingException

setCharset

public void setCharset(String string)

Character encoding to be used to encode message before calculating checksum.

setType

public void setType(ChecksumPipe.ChecksumType value)

Type of checksum to be calculated

Default value

MD5

setInputIsFile

@Deprecated
 @ConfigurationWarning(value="Please use fileSystemPipe to read the file first.")
public void setInputIsFile(boolean b)

Deprecated.

If set true, the input is assumed to be a filename; otherwise the input itself is used in the calculations.

Default value

false
